10.1 Outline of Multijunction Timers

The multijunction timers (abbreviated MJT) have input event and output event buses. Therefore, in addition to

being used as a single unit, the timers can be internally connected to each other. This capability allows for highly

flexible timer configuration, making it possible to meet various application needs. It is because the timers are

connected to the internal event buses at multiple points that they are called the “multijunction” timers.

The 32185/32186 has six types of MJT as listed in the table below, providing a total of 55-channel timers.
